I think the fact that it has all the below mentioned done to it, that makes it this valuable apparently?

You are bidding for a unique presentation signed album of Young Americans 1975..."Our Price" records website will confirm the value..the cover is personally signed by the man himself with a certificate of authenticity..the certificate confirms that the framed item has been security sealed...thisthis will sell for at least £2000 at a retail outlet....a must for all Bowie devotees....I have since been informed that the late Luther Vandross performed backing vocals on the single of the same name....
